The present paper addresses the renewed need to focus on the physics of welding to realise the full potential of the latest welding technologies which include fibre and disc lasers, friction stir welding and inverter power supplies. The approach to understanding, synthesis and generalisation in other engineering branches is reviewed, highlighting the central role of handbook type solution in the conceptual design stage. It is shown that the multiphysics and multicoupled aspects of welding exceed the capabilities of other engineering approaches and the methodology of scaling is proposed as a promising alternative. The application of scaling to friction stir welding is shown through an example in which the maximum temperature in the metal is generalised into a power law, experimental and numerical data are synthesised into a general correction factor, and secondary effects are captured as dimensionless groups.

“…In the past few years several approaches, such as tracer technique using markers [14][15][16], welding of dissimilar materials [17][18][19][20][21][22], microstructural observations [5,14,[23][24][25], have been used to visualize the complicated material flow pattern during FSW. Some computational methods including FEA [26][27][28][29][30] have been used to model the material flow as well. For example, Cui et al [13] proposed a set of equations to describe the horizontal onion-ring-like plastic flow pattern and discussed the origin for the formation of such patterns in a longitudinal section.…”

“…Some progress is being made in this area. 4 Friction stir spot welding is likely to contribute to the design of better automobiles because the method leads to the possibility of joining different metallic alloys in a mass production scenario. 5 Conventional resistance spot welds are assessed in a variety of ways including cross-tension and lap shear testing.…”

Friction stir welding and processing has come a long way since the heady days of the pioneering work done at TWI in Cambridge some two decades ago. The FSWP 2010 conference held in Lille, France, during January, had the brief to cover in this context, the process, structure-property relationships, simulation and applications. Of the large number of papers presented at the conference, a selection which dealt with welding are included in this special issue of STWJ. All of these papers went through the usual independent refereeing and editorial procedures of the journal.It is interesting that nearly 30% of research papers on FSW published since 2008 are on dissimilar metal joining; this is a large increase when compared with the average over the last two decades. It is possible that with aluminium alloys at least, the joining of similar alloys is so well established that the research focus is now shifting to the more difficult joints between materials which may have vastly different physical properties. This topic was of course covered in a recent special issue of STWJ (Volume 15, Issue 4, described in Ref. 1), and it is not surprising that the Lille meeting contains some interesting contributions in this context.
